This post is a bit late, but I decided to write it up. The Orange Pi 5 is a SBC that sports a beefy RK3588S processor and up to 16 gigabytes of RAM. To drive all of this, is a power supply that is supposed to deliver 5v @ 4 amps. Perfectly fine if you want to run just one board. But I want a cluster of these. And I'm not going to sit around with multiple power supplies plugged into a power strip, I want one power supply for multiple boards.
Unfortunately, when this device was released, there wasn't a good solution for this. Nothing really got up to 5V @4A, or if it did, only offered 2 ports. Since I needed 4 ports, I needed to homebrew something.
Here's my build materials:
4x QC4.0 QC3.0 PD USB Type-C Quick Charge Board https://www.aliexpress.us/item/3256801737033265.html
1x MEANWELL 5v 18A PSU https://a.co/d/6VtXATK
I got extra quick charge boards because they're $3 each and with the lead time from China, it's hard to get replacements if one is DOA, or if I fry one.
I 3d printed an enclosure, and started soldering the boards and wiring them to the PSU...
Nothing was too difficult here. The most difficult part was working in the tiny confines of this 3d printed enclosure.
Here's the cluster in all its glory:
I'm able to fit all 4 stacked on top of the PSU, and it takes up remarkably little room. When I ran a board on lower power PSUs, the board would boot, but the storage would accept writes without committing them to flash - very bad! But this new power supply handles them all without breaking a sweat.
This solution should be scalable to even the Raspberry Pi 5's 5V @ 5A, though you'd have to find a different charging board - I believe these specific ones will only negotiate up to 5V @ 4.5A.
